ALBERT O. BUCKIUS JR. OF CHICAGO, ILLINOIS, ASSIGNOR TO THE NATIONAL MALLEABLE CASTINGS COMPANY, OF CLEVELAND, OHIO.

JOURNAL-BOX.

To all whom it may camera.

Be it known that I, ALBERT O. BUCKIUS, Jr., a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Journal-Box, of which the following is a specification, reference being.

had to the accompanying drawings, in which- Figure 1 is a sect-ion of a journal box embodying my invention and with the lid in closed position; Fig. 2 is a section similar to Fig. 1, except that the lid is shown in openposition; Fig. 3 is. a section on the line III-III of Fig. 1; Fig. 4: is a section on the line IVIV of 1; Fig. 5 is a section on lineV-V of Fig. 3, with the hinge pin removed and the lid opened to its utmost limit, and Fig. 6 is a section similar to-Fig. 1, showing my journal box used with a lid of the ordinary M. C. B. construction.

My invention relates to journal boxes and provides a box having a lid held tightly closed against all movement except a pivotal one by both spring and wedging pressures, regardless of the wear to which the lid and meeting faces of the box may be subjected.

My invention also consists in the improved construction which shall hereinafter describe and claim.

Referring to the drawings, 2 represents the journal box having rounded bosses 3, whose surfaces are concentric with the axis of the pin aperture 4 in the hinge lug The lid 6 is attached to the journal box 2 by circular socket bearings 7 integral with the lid. which bear on the rounded bosses 3 of the box and by a hinge pin 8 of the usual construction, which may be held in place by a cotter 9. The hinge pin 8, under ordinary circumstances, is not essential, since the bosses 3 and bearings 7 are suflicientfor the pivotal movement of the lid, as will be more fully described hereinafter.

The numeral 10 designates-a spring, preferably a coil spring, which bears at one end on a seat or socket 11 on the inside of the lid 6, and at its other end bears against the lower arm 12 of thebell crank lever 13. The lever 13 has integral trunnions 14, which rotate in the sockets 15 on the lid. The upper arm 16 of the lever 13 is adapted to bear alternately against the cam surfaces 17 and 18, which diverge from the lower Specification of Letters Patent.

edge of the lug 5. Onthe lever 13 is the lug 19, which prevents accidental disengagement of the trunnions 14 from the sockets 15. The sockets 15 have an opening on their upper side, as is shown in Figs. 1, 2 and 3. l nder normal conditions there is no danger of the trunnions 14: coming out of these sockets,'because of the action of the spring 10, which tends to force. the lever 13 away' from the lid 6. If, however, the spring 10 is broken, the trunnions 14 are left free to move toward the lid and, but for'the stop action of the lug 19, the said trunnions would be able to pass around, the lips 15 of the sockets 15. To remove the lever 13 from the lid 6, the lid must first be taken from the box. The lever 13 is then swung toward the lid to a position where the lug 15) will no longer be able to come in contact with ,the lid when the trunnions 14 can be forced around the lips 15 of the sockets 15. The lever arms 12 and 16 are connected by a strengthening web 20. When the lid is in closed position, as is shown in Fig. 1, the arm 10 is held against the cam surface 17 by the action of the spring 10. The arm .16. by

reason of its wedging face 16 and of its a vertical direction, and that this wedging action compensates for wear when the initial fit of the parts has been lost through service.

Tn opening the lid from its closed'position, the arm 1,6 will move across the cam surface 17 and the hell crank lever 13 will be rotated to compress the spring 10, but when the lid has been hioved so that the tip of the arm 16 has passed the meeting point of the cam surfaces 17 and 18. it will then slide along the. cam surface 18 and will allow the spring 10 to reiixpand. The spring 10 is under compression at all times, but under greatest compression when the tip of the arm 16 is passing the meeting point of the cam surfaces 17 and 18, from which point the spring, in rexpandingthrows the lid positively either to open or closed position. When the hinge pin 8 is in place, the

upward movement of the lid is limited by the upper edge 21 of the lid coming in contact with the upper surface of the hinge lug 5. When the hinge pin 8 is not used, or has been removed, the lid 6 will turn in the same manner, owing to the fact that the socket bearings 7 and the rounded bosses 3 are held in relative position by the pressure of the spring 10 exerted through the lever 13. The bosses 3 will continue to act as the pivot for the lid 6, until it reaches the open position as shown in Fi 2. If by chance the lid is lifted beyond this position, the edge 21, in

' contact with the upper surface of the hinge lug 5,. will act as a fulcrum and the lid 6 will move into the position shown in Fig.

In this position, however, the pressure of the lever 13 against lug 5 prevents the detachment of the lid 6 from the journal box. In taking off the lid, it must be opened ,to the position shown in Fig. 2, and then,

when the spring 10 has been compressed to the point where the tip of the arm 16 will be clear of the hinge lug 5, the lid 6 may be removed.

In Fig. (3 I have shown my improved j ournal box used with a lid of the usual M. C. B. construction. In this application of my invention the usual spring 22 bears against the cam surface 18 when the lid is closed and serves in such position to hold the lid closed. As the lid is openedthe spring bears against the surface 23 and holds the lid open. In view of the frequent breakage or loss of journal box lids, the fact that a broken lid such is shown in Figs. 1-5 may be replaced by a lid of M. G. B. construction is of very great importance from a commercial standpoint.

It is obvious that various changes may be made in the device which I have shown and described herein without departing from my invention, since What I claim is:

1. A journal box having a spring seated on said lid, a cam surface on hinged lid, a

the journal box, and a two-armed lever pivoted to the lid, one arm beilr adapted to contact with said spring and the other arm being adapted, when the lid is closed, to bear upon said cam surface, the lever, the spring and the cam surface comprising wedging means to prevent movement of the lid relative to the box on a line parallel to the mouth of the box when the lid is closed,

2. A journal box having a hinged lid, a cam surface on the journal box, a bell crank lever pivoted to the inner face of the lid, and a spring seated between the lid and one arm of the lever, the other arm of the lever comprising a wedge lock between the cam surface and the pivot of the lever to press said lid downwardly along the line of the mouth of the box and to prevent movement of the lid relative to the box when the lid is closed.

3. A journal box, a hinge lug on said box having rounded bosses and rain surfaces thereon, a lid having semicircular socket bearings adapted to turn on the said bosses, a spring seated on said lid, and a two-armed lever pivoted to the lid, one arm being adapted to contact with said spring and the othercomprising a wedge between the pivot of the lever and a cam surface and being adapted in all ositions to draw said socket bearings tight y against the bosses and, when the lid is in closed position, to prevent movement of the lid across the mouth of the box.

at. A journal box having a lid, sockets on the lid, a lever having trunnions cooperating with said sockets, a spring bearing on said lever and holding it in contact with a portion of the box, and a projection on the lever adapted to bear on the lid to prevent disengagement of the lever therefrom when the springhas been rendered inoperative.
